Description
java.text.Format and its subclasses in java.text have format methods that accept FieldPosition arguments. The specifications and implementations disagree on the behavior resulting when a NullPointerException is passed in: Format.format(Object, StringBuffer, FieldPosition): specification: NPE; no implementation DateFormat.format(Object, StringBuffer, FieldPosition): specification: unspecified; implementation: pass-through DateFormat.format(Date, StringBuffer, FieldPosition): specification: unspecified; no implementation SimpleDateFormat.format(Date, StringBuffer, FieldPosition): specification: unspecified; implementation: NPE MessageFormat.format(Object, StringBuffer, FieldPosition): specification: unspecified; implementation: no exception MessageFormat.format(Object[], StringBuffer, FieldPosition): specification: unspecified; implementation: no exception NumberFormat.format(Object, StringBuffer, FieldPosition): specification: NPE; implementation: pass-through NumberFormat.format(double, StringBuffer, FieldPosition): specification: unspecified; no implementation NumberFormat.format(long, StringBuffer, FieldPosition): specification: unspecified; no implementation DecimalFormat.format(Object, StringBuffer, FieldPosition): specification: NPE; implementation: pass-through DecimalFormat.format(double, StringBuffer, FieldPosition): specification: unspecified; implementation: NPE DecimalFormat.format(long, StringBuffer, FieldPosition): specification: unspecified; implementation: NPE ChoiceFormat.format(double, StringBuffer, FieldPosition): specification: unspecified; implementation: no exception ChoiceFormat.format(long, StringBuffer, FieldPosition): specification: unspecified; implementation: pass-through The specifications and implementations need to be made consistent. Allowing null FieldPositions in general seems the best approach. ###@###.### 2005-03-03 02:45:20 GMT
